1. Introduction

1.1 Features

The Projector Blending Tool 3 is the application to support blending and stacking based on a detected image

using up to twelve projectors by USB connecting a PC and a supported camera. This application supports the

configuration below for the blending and stacking.

It is possible to overlap each image in a blended configuration by connecting a PC and multiple projectors and

then sending a Warpmap (a correction data for blending) created by this tool to a projector.

The followings are three examples for the relationship between the configuration and assigned numbers

for each projector.

(Example 1) Select “Blending” in “Select projector arrangement” to configure only blending with 2 Rows

and 1 column.

Each number is assigned from upper left to lower right in a sequential order. Those numbers which are

displayed on each window for this example are as shown in the figure above.

Projector Blending Tool 3 User Manual 15

020-103144-01 Rev. 1 (07-2019)

(Example 2) Select “Stacking” in “Select projector arrangement”.

In care of stacking, no need to care the number which is assigned on the window because all images are

projected to the same place. Those numbers which are displayed on each window for this example are as

shown in the figure above.

(Example 3) Select “Blending & Stacking” in “Select projector arrangement” to configure blending with 1

Row and 2 columns and stacking with two units.

Each number is assigned from upper left to lower right in a sequential order. As shown in right upper

figure, the projectors for stacking must allocate their positions vertically like 1 & 3 or 2 & 4. This way is

the same when put their projectors as side by side horizontally. Those numbers which are displayed on

each window for this example are as shown in the figure above.
